B0 inhomogeneity and eddy current produce image distortion in DW-EPI. Diffusion Prepared 3D FSE (DP-Cube) was developed in this study. Diffusion Prepared pulse sequence with 3 phase cycle were used to eliminate image distortion and banding artifact. Flow Compensated MPG gradient and peripheral trigger were used to make the sequence insensitive to motion. Measured ADC value was higher than literature and DW-EPI because of motion artifacts. Distortion free Diffusion weighted images were acquired with DP-Cube.
